DRY-B ATTERY-POSTIN G MACHINE Specification of Letters Patent.

Patented May 11, 1909.

To all whom it may concern:

Be it known that I, WALTER G. WAi'i'r, a citizen of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented a certain new and useful Improvement in Dry-Battery-Posting Machines, of which the following is a ful clear, and exact description.

The object of this invention is to greatly reduce the cost of securing the binding posts to zinc cups of dry battery cells.

The inventionresides in the machine shown which enables the workmen to do this work very much more ra idly than it has heretofore been done; andl this machine includes a movable table on Which'are suitable supports for the battery cells, and conveniently arranged su ports for the soldering apparatus, past whici the battery cells are carried by the movement of the table.

The invention consists in the construction and combinations of parts hereinafter described and pointed out definitely in the claims.

In the drawin s Figure 1 is a plan View of the machine. Fig. 2 is an enlarged sectional view of the upper end of a dry battery cell and the support for said end,-the support being in vertical section, and a part of the upper end of the cell being also in vertical section. Fig. 3 is a side elevation of the machine; and Fig. 4 is a detached view of thlei support for the upper end of the battery ce s.

Referring to the parts b letters A represents a tab e of circular orm which is secured to the upper end of a vertical shaft B. This shaft may be driven by the worin wheel b secured to it, and a driven Worm C suitably mounted in the frame, in enga 'ement with said wheel. The table A is pre erably secured to a plate a which is mounted on ball bearin s of any suitable construction, lone of sait? ball bearings, indicated by a', being attached to the plate a and the other, indicated by a2, being attached to the frame of the machine. Close to the outer edge of this table are a plurality of saddles D; and, associated with each one of these, is a support E, also secured-to. the table, but nearer the center thereof. This support is ofsuch height that `when a batte cell is resting upon the corresponding sa dle this support extends into the open end of the cell beneath and in engagement with the upperv edge of the zinc cup thereof. It is also in a plane above thatwhich at that time contains the carbon electrode g, so as not to touch the same. Specifically, this supportis the u per part of a cylindrical tube e which 1s oapproximately the same diameter as. the 1nte-rior of said zinc cup. The cylinder is fixed to the table; and the lower part of its outer end is cut away leaving the support E as described.

The battery cells which this machine is intended to be used with include an buter zinc cu-p G, a centrally placed carbon element g which projects above the top of said cup, and a filling of depolarizing material g moistened by an excitant. It is necessary that a binding post be secured to the zinc cup, as Well as to thecarbon element. The' zinc cups are filled, as above described, when the bindin osts are attached. The binding posts Ifl gave a split head kf adapted to embrace the to edge of the zinc cup, and a screw threade upwardly extended stem h. These binding osts are put upon the edge of the zinccup before the battery cell is put into the machine. When it is put in, the split head of the 'binding post lies in a notch e in the outer ed e of the support E, and said support just ack of this notch is rovided with a radial roove e2 whichreceives the threaded stem,l w ereby the binding post is securely held upon the ed e of the zinc cup so lonlg as the battery cel? is in the machine in t e position described.

J represents a` fixed table having a sleeve j, which embraces the upper end of the shaft B and rests u on `a nut b fixed to said shaft. The table is prevented from rotating by means of a fixed arm K having a pin I: which projects into a hole in said table. This table J is for the pur ose of supportin a box containing the inding posts, an a vessel (neither of which are shown) containing the acid used in solderlll represents the overhead reel on which soldering wire m is wound, said reel being placed at a position above the table A, so that the operator'may conveniently reach this soldering wire as it hangs down from said reel.

` N represents the solderin supplied with gas and air tg ble pipes P and R; and is su iexi lle cord or wire n. attach torch, which is rough the ilexiported by a to a' depending spring 11, in a convenient place for the operator to grasp it and direct it toward the binding post.

ln using this machine one boy will pnt the binding posts onto the edge of the zinc cups and Will place the battery cells upon the table in the position slioWn,--that is to say with the lower ends of said cups resting in the saddles D and the upper ends of said cups restingrupon the support E with the binding post in the notch e thereof. The operator who solders these binding posts on will be at another position at the table. As the zinc cups slowly moves past him he wipes the binding post and cup with the acid, and then places the end of the soldering Wire in proper position, and Wit-h the soldering torch melts enough of it for the purpose and allows the same to drop onto the binding post, whereby it is soldered to the zinc cup. When the battery cells are finished so far as this operation is concerned, they are slowly carried away from the soldering operator back to the boy, who removes them from the table and substitutes others. In the method heretofore employed for accomplishing this result, an operator would pick up a cell and put the binding post thereon, then after wiping off the same with the acid, put the cell down in a convenient position and then pick-up the solder and soldering tool, then dropping one or both of them, would ick up the c01nplete battery cell and lay 1t one side. By the use of this lnacliilietwo boys can solder on more than double the number of binding posts which two soldering operators can do according to the old practice.

Having described my invention, I claim:

1. In a posting machine, the combination of a rotatable table, means for turning it slowly and continuously, a plurality of saddles secured thereon near its outer periphery, a plurality of associated supports also secured thereon but nearer to its axis of rotation, each of said supports being an outwardly projecting arm having a substantially cylindrical top surface, and being` of such Width that it will enter the open end of the battery cell resting upon thc corre- Spondingsaddle, and `will engage with and contorni to the upper edge only ol.' said cell, substantially as specified.

2. ln a posting machine, the eoniliiination of a rotatable table having a plurality of saddles projecting upward, therefrom near its outer edge. and a plurality of associated supports which are sul'istantially cylindrical upon. their upper surface and are only of such width as to engage with the upper part otthe open end of the battery cells which rest upon the Corresponding saddles, each of said supports having in its outer edge a notch e and a gro-ove et which extends inward from said notch, the notch being adapted to receive the head ot the binding post, and the groove being itted to receive the threaded stein ot' said post, sul ,tantially as spceiied. i

3. ln a postingmachine, the co1 bination of a rotatable table, mechanism for rotating the saine slowly and continuously, a plurality of saddles secured upon said table near its outer periphery, a plurality of associated supports adapted to enter the open ends of battery cells resting in said saddles and to engage beneath the upper part of said ends, a fixture extending over the table, a reel mounted upon said fixture, a soldering torch, flexible supply pipes therefor, and a flexible support .including a contractile coil spring for normally holding'said torch in an inoperative position from .which it may be easlly more( to au operative position, substantially as specified.

ln testimony whereof, I hereunto aitlix my signature in the presence of two Witnesses.
